DUAL-TIRED TRUCK WHEEL.

Application 'tiled August 19, 1925.

This invention relates to vehicle wheels and the invention is particularly applicable to the wheels of automobile trucks, of the tvpe illustrated in inv Patent. No. 1.526.9l21

'for dual truck wheel. dated February l7 1925. In the specification ot that patent l( disclosed a tire-riin seat which was secured to the telloe of the whe/el lov studs but the construction was auch that the lateral thrust l0 of the tire-rim upon the seat in one direction is resisted onlv bv the studs The genera-l object ot this invention is to improve the construction ot wheels ot this tvpe and to provide a wheel in which `the tirenfini seat and the wheel are correlated so that the rim seat can be readilv put in place and when secured will impart all lat-eral thrust forces directlv to the wheeh the bolts heine' merelv necessary,7 to hold the tire-rim seat in place: also to provide an improved general construction tor the wheel which will 'facilitate mountinnr the tire-rim seat and the outer tire-rim on the `telloe of the wheel.

Further objects ot the invention will appear hereinafter.

The invention consists in the novel parts and combination ot parts to be described hereinafter, all of which contribute to produce an `etlicient dual'tired truck wheel.

A preterred embodiment ot the invention is described in the following` specificationy while the broad scope oi1 the invention is pointed ont in the appended claims.

In the drawing:

Fie. l is a. front elevation of a dual-tired `wheel embodying; rnv invention.

Fie; 2 is a cross-section taken through the ovlieel about on the line ot Fig'. 3.

Fig'. 3 is a vertical section through the wheel taken about on the line 3-3 of 2.

Fig'. 4; is a side elevation'ot one ot the sections ot' a rim-seat which constitutes a `teature oi? my invention.

Invpractieino; `rnv invention, l prefer to construct the wheel a steel casting'. The bodv oft the wheel is constructed with a bifurcated center disc, that is to savn it consists of two webs 2 and 3 which are disposed apart. see Figure 2. These webs have aligning; openings 4 and 5. respectively, to ref ceive a hub 6 constructed as a separate piece Serial No. 51.149.

which inav he secured hv bolts 7 to the disc` llt desired these same bolts ma;7 be utilized to secure a brake-drum 8 to the wheel.

The inner t'aces ot the webs 2 and 3 are provided with inteojral ribs ,9 which extend snbstantiallv rndiallv trom the inner edges of the openings and the inner ends ot these ribs bear against the outer tace of the hub 6. see llia'ure 2. l provide plurality `ot' these ribsn for example sin;` as shown in llinure and the;T entend inwardlv, that is, at riojht angles to the plane ot the web1 and are carried alternatelv on the opposite webs. Prcierahlv nach rih terminates short of the opposite weh leavine' slot l0 between the edile oi each rib and the opposite web. vThe presence ot' these slots is advantageous heeause it prevents the formation ot strains in the casting in the vicinitv of the huh when the metal cools. it the saine time. the v.tact that the inner ends ont the ribs rest against the huh l@fives the center ot the wheel suhstantiallv the same strength as though it had a, circumferential wall at this point. ln other words the webs taire part ot the coroprcssion forces imparted trom the hub to the wheeh and stillen the webs. `llt will be evident that a wheel having' this construc- .80 tion 'For its center can readilv he bored to ditiiercnt .diameters without substantially reducinej the strength ot the wheel.

The wheel has a larofe channel shaped rim y ll which extends continuouslv around the wheeln but this rim is provided with va pjap 12 at onepoint ot its circumference to prevent it trom interfering with passino; the indatins nipples 13 (shown in dotted linesl into place when the tires `are put on the wheel.

The rim ll has a dual character. that is to sav. it has an integral inner telloe 1.4. inteograllv connected with the inner edge ot the channel or halt-round rino "ll` and it has an outer telloe 15 which is Jformed intesrallv on the outer side ot the rim 1l.

The tires are carried on two tire-rims 16 and 17 which mav` be constructed eXactlv alike. The inner telloe 14 is provided with an inclined face 18 which operates as a rim seat and upon which rests a corresponding inclined seat-tace formed on the inner tace of the inner tire-rim 16. Near its outer edge,

fio

the tire rim 16 is secured in place by the usual Wedge ring 19 held in place by clamps 2O and stud bolts 21.

In order to mount the outer tire-rim 17 in place, I construct the outer felloe 15 with a circumferential felloe-member 22, see Figure 2, which extends continuously around the Wheel. This felloe-member receives a rim-seat 23 in the form of a ring having a groove 24E on its inner face which lits to the felloe member 22 with a machine lit. This rim-seat 23 is constructed in sections, preferably tvvo sections 25, and each section is constructed so that it will come into place on the felloe member 22 by a radial inward movement. In addition to this, I provide means for preventing circumferential movement of the sections 25 on the felice-member 22, and for this purpose I provide an interlocking connection between the felloe and` the sections 25. This is preferably accomplishedby providing a plurality of studs 26 which project laterally from the felice-member, and also by providing sockets 27 on the sections 25 Which receive the studs When the sections are shoved into place. The sockets co-operate with the studs to prevent circumferential shifting of the sections25, and when the rim 17 is in place they will' be securely held on the Wheel. I-IoWever, in order to provide additional security for the sections 25, I prefer to provide the studs 26 With nuts 28 which may be clamped up against the lugs 29 in which the sockets 27 are formed.

The rim-seat 23 is preferably formed with an inclined or conical seat-face 30 upon Which seats a corresponding seat face on the inner face of the tire-rim 17. Any suitable means may be provided for securing the other edge, or outer edge 31 of the rim 17 to the felloe. This construction may be a substantial counterpart of that illustrated in connection with the innei tire-rim 16, that is to say, involving th-e use of a wedge-ring 32 held in place by clamps 33 and studbolts 34.

. The tires may be held on the rims in any suitable manner, for example, by means of standard construction illustrated.

It will be evident that when the rim-seat 23 is not in place. the inner tire-rim 16 may be readily passed over the outer felloe 15 in putting it in place. After the inner rim with its tire has been put on, then the rimseat 23 should be put in place, and the outer tire rim 17 mounted on the rim-seat and then secured to the wheel at its outer edge 31.

Whe-els embodying my invention may be readily made of cast steel with a Wall thickness of one quarter inch for the Webs and the other parts of the Wheel producing a Wheel of about 125 pounds Weight which will support a load of 6 tons.

The Webs 2 and 3 are disposed suiiiciently far apart to give suiicient strength to the disc as a support for the arched or halfround rim l1. In other Words, the web 2 is near enough to the middle plane of the Wheel to give suflicient strength to the overhanging portion of the rim.

It is understood that the embodiment of the invention described herein is only one of the many embodiments this invention may take, and I do not Wish to be limited in the practice of the invention, nor in the claims, to the particular embodiment set forth.
